Any suggestions...please feel free...

You're putting a SLI video card (9800GX2) into a Crossfire motherboard. You could probably get by with the P5Qand save $80. And for a single 9800GX2 a 600W class PSU should be plenty of power and save $20 Corsair 650TX.

What games and what monitor size/resolution will you be using? For $470s worth of GPU power you could get more performance in certain games with 2x 4850Crossfire setup in that ASUS P5Q Deluxe. For example in CoD4 @ 1680x1050 4XAA: 9800GX2=125FPS vs 4850CF=147FPS 1920x1200 9800GX2=108FPS vs 4850CF=130FPS. You'd also save up to $130 Sapphire HD 4850 $165 after rebate

Corsair 650TX would also be good for 2x 4850CF.

You'll want this bracket for the Xiggy:

There is a new review up on the front page for the P45, you might want to review it.

I believe the WD is the better drive with better support, even though the warranty is shorter:

32MB, 16MB, does not matter much.

Not a very good deal on the video card. Consider crossfire 4850s at $400 for two, or get a GTX280:

Ya I wasn't v ery sure about the 9800GX2 video card as far as performance/price ratio. Right now I am running a BFG 9800GTX video card, how does this compare to the 9800GX2 video card? Also i'm not familiar with the Crossfire Technology, what exactly is it? What would you suggest, the two 4850s or the GTX200? Thanks for your help.

I would go with the two 4850s and an X38 or X48 board.

For a comparison of the 9800GTX, 9800GX2, CF 4850s and GTX280, look at the image in WR2's post and the following articles:

Oh, and CrossfireX is similar to SLi except with AMD(ATI) cards. It's more flexible, though and can work with a wider range of cards together (like 3850 + 3870), and is expandable up to four cards at the moment (provided you have the slots to handle it). The performance of Crossfire seems to have lagged SLi slightly, but recently, it's looked like most of the kinks have been worked out and it's not only a viable option, but a great bang/buck solution, as CF 4850s beat out a GTX280 for less money!
